On Windows, when an executable file named cmd.exe
is located in the current working directory it will be called by the Process
class when preparing command arguments, leading to possible hijacking.
The Process
class now uses the absolute path to cmd.exe
.
The patch for this issue is available here for branch 5.4.
We would like to thank Jordi Boggiano for reporting the issue and Nicolas Grekas for providing the fix.
